Core offerings include:

Autonomous landing craft
Unmanned surface vessels

Leadership Comments

"Building unmanned systems at scale inside the theater, on the industrial base and supply chains an ally already has, does two things at once. It solves a problem the people running these missions have today, and it puts decades of allied know-how to work on American reindustrialization, " said Nhat Lieu, Co-founder and CEO, Bulwark Dynamics.

"In a contested environment, the attributes that make a logistics platform efficient are the same ones that make it a target: large, crewed, concentrated, and tied to a handful of fixed nodes. Sustainment has to survive to matter. Caravel takes people off the most exposed leg of the run and spreads the delivery across many low cost hulls, so losing one is a bad day rather than the end of the resupply, " said Nhat Lieu, Co-founder and CEO, Bulwark Dynamics.
